From most energy efficient to least energy efficient:

LED bulbs (relativly new)

Fluorescent bulbs (normal "energy savings" bulbs)

Halogen (used for high intensity lighting)

Incandescent bulbs (regular bulbs)

Energy efficient light bulbs are bulbs that convert a higher percentage of electical power into light. All bulbs also create waste heat, where energy is radiated as infrared. The less efficient bulbs tend to be "hotter" because of the amount of power "wasted" this way.
